ROPE-GRIP.

Specification of Letters Patent.

Patented June 27, 1916.

Application filed April 1, 1914. Serial No. 828,924.

T 0 all whom it may concern:

Be it known that I, ALrnoNsn VANDER- DONGK, a citizen of the UnitedStates, residing in the borough of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Iniprovements inRope-Grips, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in rope grip, and may be employedfor use in combination with hoisting pulleys, clothes lines, automobilebrakes, dumbwaiters, awnings, and various other uses.

In the accompanying drawings, I have illustrated an application of myinvention although of course it will be understood that the inventionmay be applied in many other uses.

In the said drawings, Figure 1 indicates the application of my inventionto a hoisting pulley in which it is shown partly in'cross section andpartly broken away. Fig. 2 is a view looking at right angles at Fig. 1.

Referring to Fig. 1, 5 indicates my improved form of pulley or blocksuspended in any suitable manner as by the hook 6. 7 in dicates thepulley wheel from which the material is suspended such as the weight 8by any suitable means such as the rope 9. 10 indicates another pulleywheel over which passes the control rope 11 secured to the brakemechanism 12. The lower portion of the casing of the pulley or block, itwill be observed, terminates in a sort of lip 18 and the lower portionof the brake mechanism, it will also be observed, is provided with teethsuch asll which are adapted to bear against the rope 9 and force thesame against the lip 13 of the casing of the pulley. 15 is acounterweight or safety lever also pivoted upon the bearing 16 with thebrake and which serves to normally keep the teeth 1e of said brakeagainst the rope 9. From this it will be seen that as the weight 8 iselevated by pulling on the right hand side of the rope 9, looking atFig. 1, the free end of the rope 9 may be released and the weight willremain 1n 1ts hoisted position, belng securely bound between the hp 13of the casing and the teeth 14: of the brake by virtue of the coun-.

ter-weight or lever 15. The upper portion of the counter-weight, it willalso be observed, is provided with teeth such as 17 which with the brakeserve as a double clutch to additionally bind the rope 9. To release therope 9 and its weight or the material socured thereto, it is onlynecessary to pull upon the brake rope 11, engaging the top of the brakeat 18 as shown, whereupon the teeth 14 17 are pulled clear of the rope 9and allow the weight to descend freely. By this means it will be readilyseen that great weights may be raised upon a single pulley in a blockand the weight of the same taken off the arms of the person hoisting thesame by means of the brake as aforesaid. It will also be readilyunderstood that after the weight has been taken to the desired point andremoved, or at any stage in the proceeding, the same may be released andallowed to return to its original position.

Of course it will be understood that the device is susceptible of use inmany applications not shown or described herein and the invention is notlimited to the particular applications herein set forth.

I claim:

A. pulley adapted to receive a rope and having a pulley block frame, abrake member upon said frame adapted to retain the pulled side of saidrope except when same pulled or released, and means for releasing thesame, and a weighted engaging member incombination with said brakemember also adapted to retain said rope upon the pulled side except whenreleased therefrom.

In testimony whereof I hereunto allix my signature in the presence oftwo witnesses.

ALPI'IONSE VANDERDONCK.
